JTG-ZF-C34/JTGB-UF-C35Ex Point Type UV & IR Flame Detector
Summary
JTG-ZF-C34/JTGB-UF-C35Ex point type UV & IR flame detector (hereinafter referred to detector) adopt flame multispectral signal acquisition method/full frequency wave analysis technology, it avoids the weaknesses to interference of traditional detectors. The detection environment is monitored by increasing slope signal detection technology (PAM), which improves the stability and sustainability of the detector. It ensures that the detector can quickly identify and detect fire while minimizing false alarm. The detector is suitable for all kinds of places, such as oil depot, wine depot, aircraft hangar, chemical equipment site, military equipment site, liquefied gas station, power station, tunnel, etc. With high anti-interference ability, can work well in indoor or outdoor environment.
The detector adopts six-wire connection style (two power lines, two fire touch spot lines, two fault touch spot lines), In case of alarm, the fire touch spot changes from normally open to normally closed. In case of fault alarm, the fault touch spot changes from normally closed to normally open. It can be connected with the fire alarm system of any manufactur

Use and Maintenance
Wiring:
- The wiring is shown in the picture. The red and black wires are connected to the positive and negative electrodes of the DC24V power supply.
- The yellow and white line is the contact output of the alarm relay, which closes when alarming.
- The green and blue line is the output of the fault relay, which is fault relay output, normally closed, fault disconnect.
- If module has terminal resistance, connect blue and green lines, yellow and white lines and terminal resistance, Resistance should be installed as close as possible to the detector. It is not recommended to install resistors near modules.

Installation Requirement
- Overlooking installation: Depression angle <45°
- Installation distance:The protection distance of detectors in oil sites is 3m ~ 5m. The protective space of chemical sites is 5m ~ 7m. The protection distance of smelting site is 7m ~ 10m. The protection spacing of power sites is 2m ~ 10m.
- There should be no obstacles blocking the line of sight of the detector in the fire area. If the obstacles cannot be avoided, the number of detectors should be considered to achieve no-dead Angle detection.
- Detector shell should be ground.
